You know what?
To be accurate it's not "WE" who don't know what is a woman.
We: the majority of peoples, normals persons.
Them: A bunch of "intellectuals-educated-persons" who thing all in the world is about their ideology, and who don't even know how the real world works, because they live in their little environnement, their littles urbans "safe spaces", their offices, their campus, or classrooms. They are the peoples who just lives and want to see peoples who look or think like them, and last but not the least, who are from the same wealthy class, even if they deny it.
Peoples who refuse contradictions, or don't want to see the real world.
They are like the aristocratic class in France before 1789, or like byzantins theologist who argued about the properties of angels, when the turkish empire was at their gates.
